When considering which switch to purchase, it would be advisable to check whether a wireless version of the switch you require is available. Using a wireless switch will allow an individual to move the switch to a suitable position without also having to relocate the accompanying switch cable. 

In its most common form, a wired switch is a button shaped device with a 3.5mm jack plug lead. To access a PC, the lead connects to an interface, or it can be plugged directly into a switch adapted product, an interactive toy, for example.

It may be necessary to consider a different type of switch when a button switch proves not to be suitable for the individual. In this respect there are many specialist switches available, in different shapes and sizes, that require varying amounts of pressure to activate.

Switch access is commonly used by individuals with motor disabilities and cognitive disabilities, such as cerebral palsy, multiple sclerosis and autism, who cannot access a mouse, keyboard, touch screen or alternative access method.

There are various factors to consider when selecting the correct switch. Whether choosing between size, colour, wired or wireless and the activation force required to press the switch, it’s important to identify the individuals needs and requirements to determine which switch is the most suitable for them.

The computer mouse is so familiar to all of us that it has become a perfectly sensible and easy way to use our computers. So much so that when we ask someone with learning difficulties or disabilities to use a computer we seldom think about the complexity of the task we are asking them to do. 

Just operating a mouse involves complex motor, sequencing and spatial skills. For some software the mouse skills may be at a higher cognitive level than the program they are trying to use. Substituting a different device such as a roller ball may make the physical task easier but will not simplify the cognitive task. 

The term "visual impairment" is used to describe a wide range of conditions which affect clarity of vision and visual field. By using a computer with appropriate software and hardware the visually impaired user can be given access to standard resources.
